To all whom it may 00%06'771.)

Be it known that I, EDWARD VINCENT MoCan'rH-Y, a citizen ,of the United States, and a resident of'the cityof Chicago, county ofCook, and State of IflllIlOiS, have invented a new and useful Improvement in. Devices for Cleaning Floor Drains, of which the following is a full clear, and exact description.

My invention relates to improvements in a device for cleaning floor drains, and it consists, in the combinations, constructions, and arrangements herein described and claimed. I

An object of myinvention is to. provide a. means of the character described which may be used for loosening accumulations of foreign substances in a floor drain so that the. accumulations may be forced down through the drain and through'the gooseineck trap usually provided in drain connections. I

A further object of my invention is to provide a device of the type described in which particularly novel construction is employed for breaking up andloosening com.- pact deposits of drain trap accumulations such as grease and the like which is usuall found in'a drainfor a garage floor.

it further object of my invention is to provide a. device'of the type described that is durable in. construction, compact inform and thoroughly practical for the purpose intended, r

I ()ther objects and; advantages will appear in, the following specification, and the novel features of the invention will beparticularly P i t d ut t e am n ed My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a sectional view of a floor drain showing my improved cleaning device in an operative position.

Figure 2 is an enlarged view along the line 2-2 of Figure 1,

Figure 3 is a sectional view along the line 33 of Figure 2, 4

Figure 4 is a sectional view along the line 4-4: of Figure 2, and

Figure 5 is a sectional View of one of the work engaging members of my invention.

In carrying out my invention I make use of a rigid rod 1 having a handle portion 2 at the upper end thereof and having threads 3 a e l er and, T th eads 3 p ovid means; for securing the work engaging, part of my cleaning device thereto.

This, part consists of a brass disc 4 having an upstanding marginal wall portion 5;; The wall 5 extends above the top surface Gof the disc/i substantially three-.eighthsof an. inch. j r f A segmental part of the disc l is cut away therefrom leaving only the hub portion7 thereof at that part. The hubportion, 7 has an internal threaded bore 8 which is, arranged to receive the threads 3 of, the rod member 1. I I

A portion 9 in the form of a boss ispr-o; vided? on the disc 4; and has its top surface level with the top, wall 10 of the marginal wall 5 (see Figure 3). A pair of teeth 11 are formed on the outer wallfof the bossv 9.

and have the points; 12 thereof in theplane ofthe bottom surface 13 of the disti l. Thus ment with a substance, that substance is broken up and caused to move upwardly on the inclined front surfaces 13-of the teeth, and hence over the boss, 9 upon the surface f the disc.

Means for delivering such broken substance from the surface 6 of the disc is pro;

vided, in a bossed portion. 15 at the opposite edge of the disc t at that edge opposite to the front wall 1a is cut away at an, angle soas to. virtually provide an overhanging portion of the. disc in, the boss 15.

'From the foregoing description of the various parts of the device, the operation thereof may be readily understood. My device is primarily intended for use in loosening the compact accumulation of foreign substances such as grease, threads, mud and the like which may be expected to accumulate in the drain pipe of a floor drain just in front of the gooseneck fixture 17 ordinarily employed with such drain pipe. The ordinary type of floor drain is shown in the drawing of Figure 1 at 18. An accumulation of foreign substance is indicated at 19.

The device is inserted in the drain pipe 18, as shown in Figure 1, and the handle 2 turned in a clockwise direction. This causes the teeth 11 to bite and break up the when the teeth 11 are, moved; into engage.

adjacent parts of the accumulation 19, which loosened accumulation will be forced up over the surfaces 13 of the teeth and over the boss 9 and upon the surface 6 of the disc.

Continued rotation will cause large quantities of the accumulation 19 to be broken up so that with proper flushing it may be forced over the gooseneck portion 17 and down through the drain pipe.

When the surface 6 has been entirely covered with such broken and loosened accumulation further rotation thereof will cause it to pass up over the inclined surface 16 of the projection 15 and back beneath the disc. At this time the disc should be withdrawn by movement of the rod 1 and a plunger, such as shown in Figure 5 and indicated at 20, is attached to the rod 1 by means of the thread portion 3-. This plunger 20 consists in a metal body portion 21 hav ing internal threads 22 which receive the threaded portion 3 of the rod 1 and a heavy coating of soft rubber applied to the ex posed parts of the body 21. This plunger is forced downwardly upon the loosened accumulation 19 with suflicient force to cause the accumulation to move over the gooseneclr 17 and down over the drain. Atthis time sufficient quantities of water should be poured down through the drain 18 to thoroughly flush the drain.

I claim:

1. A device of the character described comprising a work engaging member having the form of a disc with a segmental portion thereof cutaway, teeth formed on said disc and extending into the cutaway portion of the disc, said disc having a marginal wall extending upwardly therefrom, a removable handle member for supporting said disc, said teeth being constructed so as to engage with and force substances upon the upper surface of said disc when said disc is rotated, and an upwardly extending boss on said disc at that portion opposite to thetoothed portion, and an inclined sur face merging with the top surface of said above the top surface of said disc, said disc.

having a marginal wall extending upwardly therefrom, a removable handle member for supporting said disc, said teeth being constructed so as to engage with and force substances upon the upper surface of said 'disc when said disc is rotated, and an upwardly extending boss on said disc at that portion opposite to the toothed portion, and an inclined surface merging with the top surface of said disc whereby substances on said disc may be moved up the inclined surface and p out of engagement with the disc when the disc is rotated.

3.1-1 device of the character described comprising a work engaging member having the form of a disc with a segmental portion'thereof cutaway, teeth formed on said disc and extending into the cutaway portion of the disc, said disc having a marginal wall extending upwardly therefrom, a removable handle member for supporting said disc, said teeth being constructed so as to engage with and force substances upon the upper surface of said disc when said disc is rotated, the top surface of said teeth being contiguous with the marginal wall, and an upwardly extending boss 011 said disc at that portion opposite to the toothed portion, and

an inclined surface merging with the top surface of sald disc whereby substances on said disc may be moved up the inclined surface and out of engagement with the disc when the disc is rotated.
